Dukes is a coal miner's son who grew up singing in the church choir as a boy and later made his way through college performing around Bowling Green, Ky.

He has a degree in special education and taught in the Williamson County, Tenn., school district for three years before making music his full-time profession.

He has opened for acts including Charlie Worsham and Billy Dean.

Though his roots are in gospel, the singer/songwriter says his influences vary from Nirvana to Garth Brooks, Tom Petty to Eminem.

"I really get into the storytellers," he says in an online bio. "It's how a story is shared through music that relates to everyone."

Other shows are scheduled Sept. 20 with veteran Chattanooga party band The Beaters and Oct. 18 with a group still to be confirmed, according to organizers. Depending on how the first three shows go, more may be in the offing.

"We are going to introduce Camp Jordan Jams this fall, and if we have the success we anticipate we will schedule more free concerts in April, May and June," says Stump Martin, director of East Ridge Parks and Recreation. "Camp Jordan is a happening place to be all of the time. However, with a Bass Pro Shop scheduled to be built adjoining the park, we can expect even more activity in the future."

The free shows will take place on Saturdays, with the headline act performing from 7 to 9 p.m.

"We want the people with their chairs and blankets, as well as the many car clubs and motorcycle riders to show up and have a good time."

Vending and political spaces are available for a $50 donation per concert to the East Ridge Needy Child Fund. To reserve a spot, call Janet Middleton at 423-490-0078.
